Coordinate system

This content is not available in your language yet.

All ClaudeUnreal tools that accept positions, rotations, scales, or colors assume Unreal Engine’s conventions.

Position and scale

Section titled “Position and scale”
  • Axes: X = forward (red), Y = right (green), Z = up (blue)
  • Units: centimeters. 100 means 1 metre. A default cube is 100 × 100 × 100.
  • Handedness: left-handed.

Rotation

Section titled “Rotation”
  • Reported as [Pitch, Yaw, Roll] in degrees.
  • Pitch rotates around Y (nose up/down), Yaw around Z (turn left/right), Roll around X (tilt).

Colors

Section titled “Colors”

RGBA floats in the 0.0–1.0 range (not 0–255).

{"R": 1.0, "G": 0.5, "B": 0.0, "A": 1.0}
